different results showing up for the IC and NIC

We have run the [E2E OMR workflow](http://ddmal.music.mcgill.ca/e2e-omr-documentation/hints.html) with Interactive Classifier and with Non-Interactive Classifier for Salzinnes 028r folio in Rodan2, using the same training data, and different results were showing up on Neon, as follows:

028r with IC:

028r with NIC:

And IC didn't identify any clefs, while NIC identified several C clefs and one F clef, which seems better. But we were not sure why they have different results, as we didn't do any classification in IC.
